Primary Tumor

A primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass.

Famous quotes containing the word primary:

    “Europe has a set of primary interests, which to us have none, or a very remote relation. Hence she must be engaged in frequent controversies, the causes of which are essentially foreign to our concerns. Hence, therefore, it must be unwise in us to implicate ourselves, by artificial ties, in the ordinary vicissitudes of her politics or the ordinary combinations and collisions of her friendships or enmities.”
    —George Washington (1732–1799)
